Question

The following data describe an initial and final state for an ideal gas. Given that the amount of gas does not change in the process, what is the final pressure (atm) of the gas?

A) 1 atm
B) 2 atm
C) 3 atm
D) 4 atm

Answer 1

The final pressure of the gas is approximately 2.65 atm.

This correct answer is none of the above.

Step-by-step explanation:

To determine the final pressure of the gas, we can use the ideal gas law equation: P1V1/T1 = P2V2/T2. Since the amount of gas does not change, the number of moles (n) stays constant.

Therefore, we can simplify the equation to P1V1 = P2V2. Rearranging the equation, we have P2 = (P1V1)/V2.

Substituting the given values, we have P2 = (1.82 atm x 8.33 L) / 5.72 L = 2.65 atm (approximately).

Therefore, the final pressure of the gas is approximately 2.65 atm.

This correct answer is none of the above.
